Friendly Tips:

According to the feedback of the most of customers, the hose barb and the reservoir box of the Snow Foam Lance is easily damaged:

1, Due to the copper material, the hose barb and the reservoir box is easily out of shape during transport and it is difficult to be repaired.;

2, In the course of use the snow foam lance, if you incautiously drop it in the ground, the product will be easy to damage.

3, The copper rubs against the plastic bottle so that the screw thread of bottle is easy to damage.

Now we decide to change the copper material to the Nylon PA66 material. The advantages are as follows :

1.Features of the Nylon PA66 material:

a. high crystallinity and perfect melting point;

b. good surface hardness;

c. high abrasion resistance and tiny friction;

d. excellent self- lubricity and noise reduction;

e. work stable at low temperature and can work under 100℃;

f. non-toxic, odorless, non-rusty;

g. nonflammable and self-extinguishing;

h. good weather-resistance.

2.The test shows that, compared with the copper one, the Nylon PA66 reservoir box is more resistant of being squashed and more throw-proof for its special material.

3, The Nylon PA66 reservoir box is less abrasive to the bottle, the damage could be neglected in most cases.

4, The product is easier to pass the customs clearance procedure for the lighter weight.

Please pay attention, at present there are both the Nylon PA66
reservior box and the brass one,so we would send these two kinds by random. 
In the future few months, we would only send you the plastic one. Thanks for understanding in advance.

Colorless stands for Brass Adapter, Black Color stands for Plastic Adapter. As you can see from the photo when you make the selection.

Brass Adapter and Plastic Adapter are same size, they are just made in different material, so you can select either one.

This listing is a 3 units package. it means there are 5 units included, and each unit is packaged in individual boxes unless you request us not to.

The Karcher K Series adapter are all made in plastic, not brass. the brass version means the plastic adapter with brass thread inside, the plastic version means the plastic adapter is with plastic thread inside.

so the key difference is the thread part material, not the adapter itself.

the foam lance is with our new plastic adapters, this plastic adapter is much better and more convenient to use, because there are two bolts on the connection bar for you to tighten the connector on foam lance body, you can lock the connector with the foam lance body at a correct direction you want.

the material of the adapter is same as per the pressure washer’s original spray lance, so it is same durable, same compatibility as per the original spray lance of pressure washer.
